Color Mixing a Witches Brew {Halloween Activity}

This color mixing activity is great fun for preschoolers and toddlers because it involves a lot of messy, water play!  But it also makes for a fun Halloween activity as your kids stir up their own witches brew.  We are always looking for Halloween fun at Kids Activities Blog!

Color Mixing

Double, double, toil, and trouble;

Fire burn and cauldron bubble!

Little ones have fun stirring up a Wicked Witches Brew;

And you’ll sneak in some Color Mixing Learning, too!

Halloween Activity


  • water (optional: use colored ice cubes instead)
  • food coloring
  • spoons or other mixing tools
  • bowls or a cauldron

Witches Brew

Fill a few bowls with colored water – you’ll only need a drop or two of liquid food coloring – and let your children take turns pouring the colors into your main bowl.  We used a porcelain roasting pan for more surface area (i.e., more room to observe more colors mixing).

Halloween Fun

The Way We Learned:

  • Hypothesis:  Before pouring in a new color, we guessed what the mixed color result would be.
  • Observation:  We watched the colors mixing together.
  • Conclusions: After a few practice *potions*, we became better at guessing what the color results would be.  We also took turns guessing whether the color would get darker, lighter, or more heavily tinted with a particular color.

Muddy black was the favorite color, of course!

To really explore the concept of color mixing, try limiting your child’s choices to just two planned colors, like red and yellow, and watch them swirl to make orange.  Get a fresh bowl of water and repeat your experiment with a new pair of colors.

To make the experiment even more fun, use colored ice cubes and watch the colors slowly dissolve together.  Using ice cubes helps the children view the mixing more easily since you can achieve an area of one color, an area of the second color, and an area where the two colors intersect.
